CPU Vcore/Dram Voltage/+3.3V/+12V
Displays the current system voltages.
CPU/System Temperature
Displays current CPU/system temperature.
CPU/System FAN Speed
Displays current CPU/system fan speeds.
CPU Warning Temperature
Sets the warning threshold for CPU temperature. When CPU temperature exceeds the threshold, BIOS will
emit warning sound. Options are: Disabled (default), 60
CPU/System Fan Fail Warning
Allows the system to emit warning sound if the CPU fan or system fans are not connected or fail. Check
the fan condition or fan connection when this occurs. (Default: Disabled)
CPU Fan Control Mode
Speci es how to control CPU fan speed. This item is con gurable only when CPU FAN Speed Control
is enabled.
Auto Lets the BIOS automatically detect the type of CPU fan installed and sets the optimal CPU
fan control mode. (Default)
Voltage Sets Voltage mode for a 3-pin CPU fan.
PWM Sets PWM mode for a 4-pin CPU fan.
Note: The Voltage mode can be set for a 3-pin CPU fan or a 4-pin CPU fan. However, for a 4-pin CPU
fan that is not designed following Intel PWM fan speci cations, selecting PWM mode may not effectively
reduce the fan speed.
CPU Fan Speed Control
Allows you to determine whether to enable the CPU fan speed control function and adjust the fan
speed.
Normal Allows the CPU fan to run at different speeds according to the CPU temperature. You can
adjust the fan speed with EasyTune based on your system requirements. (Default)
Silent Allows the CPU fan to run at slow speeds.
Manual Allows you to control the CPU fan speed under the Slope PWM item.
Disabled Allows the CPU fan to run at full speeds.
Slope PWM
Allows you to control the CPU fan speed. This item is con gurable only when CPU Fan Speed Control
is set to Manual. Options are: 0.75 PWM value /
1st/2nd/3rd System Fan Speed Control
Allows you to determine whether to enable the system fan speed control function and adjust the fan
speed.
Normal Allows the system fans to run at different speeds according to the system temperature. You
can adjust the fan speed with EasyTune based on your system requirements. (Default)
Silent Allows the system fans to run at slow speeds.
Manual Allows you to control the system fans speed under the Slope PWM item.
Disabled Allows the system fans to run at full speeds.
Slope PWM
Allows you to control the system fan speed. This item is con gurable only when 1st/2nd/3rd System
Fan Speed Control is set to Manual. Options are: 0.75 PWM value /
